The Interface

Overview

The Weather Editor allows you to create weather presets to use within weather volumes. There are several options to use, including the Skybox, Sun, Clouds to Post Process, and Snow/Water Levels.

You can create different types of weather such as Constant, Day/Night Cycles, or Modifiers. Also, with the editor open, you can preview the weather in-editor, without having to set up a weather volume.

Setup

To access the weather list, look for the W (for Weather) in the Library Toolbar.

To create an empty weather list, right click on the Weather List → Add.

Time navigation	Allows you to jump to a specific time in the timeline. From 00:00 to 24:00. The arrows allow you to jump one hour in the timeline.
<- ->	Jump to the next/previous key or to the next/previous hour.
Constant Weather	Weather type. Without the ‘time’ component. Managing such weather is much easier when you’re working with a linear level. Set the selected weather to Constant Weather. Constant weather does not have Day/Night Cycles, and has fixed values. Good for indoor environments where day/night is not perceivable and does not affect the scene.
Modifier Weather	Instead of doing full weather blends and dealing with this complexity, you can modify only the needed values with the Weather Modifier. For example, you have an indoor environment on an outdoor level that normally has dark and dense fog no matter the hour. This way, you can change just the fog while the rest is taken from the base weather. Modifiers can be Constant as well as 24hr looped.
Always On Top	Set the Weather Editor Window to be always on top of the editor.
No Preview	Toggles the preview in the editor.
InGame Preview	Show weather's changes in real time.
Set Sun Position	Set the sun's position in the viewport.
Save All	Saves all changes made to the weather.
Import env	Import parameters of another weather preset.

Weather List Density

List of available weather presets. You can also create folders for organization. All weathers have corresponding .LUA files under /content/weather/

Prop List

Adds a new non-editable curve on the graph from the desired property. Used to create similar curves on graphs. A description of all options can be found in the Properties section.

Graph Editor

A graph with curves for one or more properties.

Average color values for: sky, fog, sunlight, and selected option with timeline.
Vertical value scale and boxes with colors of curves.
A graph with selected curves and background curves from the prop list.
Timeline.
Name of the texture (skybox, HDR, etc.) for the current weather preset.

Properties

Allows you to edit the weather preset's properties. For Constant Weathers, values are constant and keyed once. All weather properties are keyable.
For Day/Night Cycles, you can manually key values by setting time on the Timeline, and adjust the value in the properties window.
For Modifier Weathers:
- First, select the "main weather" that you are going to add a modifier to (it should appear as a W on the right side of the name, in the Weather List).
- Select the modifier weather (it should appear as an M on the right side from the name, in the Weather List).
- Now you're previewing the modifier weather.
- Weather modifiers allow you to override specific values while maintaining the originals (from the main weather).

Property name			Description	Notes

Property name			Description	Notes
Sky	Texture		Texture of the skybox.	For Day/Night Cycles, you can also change the skybox in "real-time" if needed.
	Color	RGBA	Sky hue. A – sky intensity.	Important! In the indoor weather, you need to turn off the sky (RGBA=0) to avoid problems with reflections and leaks.
	Rotation		Rotation of the skybox.
Fog	Fog Color	RGBA	Main Fog Color.
	Fog Color 2	RGBA	Second Fog Color.
	Fog Density		Total Fog Density.
	For Variation +/-		Fog Unevenness.	Creates areas of greater and lesser fog density.
	Fog Turbulence Scale		Size of an uneven area (specified by the previous parameter (For Variation +/-).
	Height Base		Sets the height in meters, below which the fog density is uniform and maximum, and above which it begins to decrease.
	Height Based Density		Sets the intensity of fog density reduction above the Height Base point. If set to a negative value, the fog will 'turn over'
	Scattering Phase		Sets the shape of light scattering by the fog (from soft even dispersion (0), to sharp intense (1)).
	Density Curve		The intensity of the increase in fog density in relation to the distance from the player.	Use this to make the air foggy or clear. We recommend avoiding the Near Plane parameter. There must always be a thin layer of visible air (unless we are making a game set in outer space with no atmosphere).
	Fog Saturation		Fog saturation.
Snow Level			Controls the height of snow on the level.	Objects that have a special shader will be affected by this. If there is no object, this value won't change anything.
Water Level
